Technical field

The present invention relates to a kind of valve bodies, and in particular to triple-use valve.

Background technique

With the gradual perfection of coal-mining technique, high-grade common coal mining face is extensive in China using hydraulic prop top plate Using and achieving good technical economic benefit, hydraulic prop is a kind of support equipment of new environment-friendly type, both can be with Metal hinge top beam is mating to use face timbering top plate and fully-mechanized mining working supporting end for high-grade conventional mining and big gun, A column can individually be done or other temporary supportings are used, it has also become one of main support apparatus of coal working face, in monomer hydraulic Using triple-use valve is arrived on pillar top plate, triple-use valve can be good at carrying out the support of hydraulic prop plate, but the prior art In triple-use valve use when carrying strength it is inadequate, the adjustment in gap can not be carried out, affect the using effect of triple-use valve.

Summary of the invention

The present invention is inadequate in order to solve to carry strength when triple-use valve existing in the prior art uses, and can not carry out The adjustment in gap, the technical issues of affecting the using effect of triple-use valve, it is proposed that one kind can preferably carry out holding for strength It carries, while can carry out floating and finely tune the triple-use valve in gap.

The technical solution of the present invention is as follows: triple-use valve, is provided with valve cylinder, the valve cylinder is divided into left valve cylinder and right valve cylinder, institute The right valve cylinder stated is caught in left valve cylinder, is provided with oiling valve body in the left valve cylinder, is provided with list on the inside of oiling valve body To valve base, it is provided with limit sleeve between one-way valve seat and oiling valve body, the side of limit sleeve is provided with gland nut, It is internally embedded steel ball in gland nut, abutting in the side of steel ball has volute spring, the company of being provided on rear side of volute spring Screw rod is connect, valve seat is provided on rear side of connecting screw, is internally provided with safe needle in valve seat, is arranged in the side of valve seat There is safe valve pad, spring base is provided on rear side of valve seat.

The outside of the connecting screw surrounds and is provided with unloading valve spring.

It is provided with unloading valve chamber on the outside of the left valve cylinder, is embedded with unloading valve pad feather valve is intracavitary.

The access section in right valve cylinder and left valve cylinder is provided with seal member, and the seal member is No.1 O shape Circle.

No. two O-rings are provided between the right valve cylinder and valve seat.

The side of the spring base is provided with regulating member, forms clip cavity between the regulating member and spring base, Safety valve spring has been embedded in clip cavity.

The regulating member is adjusting screw, is provided with extension boss in the adjusting screw, the extension is convex Platform extends into inside safety valve spring.

The outer surface of the right valve cylinder is provided with seal groove, is embedded in No. three O-rings in seal groove.

It is provided with hexagonal guide sleeve between the spring base and valve seat, is provided between hexagonal guide sleeve and spring base Float ball.

The invention has the advantages that left valve cylinder and right valve cylinder are used detachable structure, it can be realized and used at any time for three Maintenance inside valve, maintenance cost reduces when triple-use valve use, and volute spring is provided in valve seat, can be realized three use Valve using when can be become larger with bearing capacity amount, the side of volute spring is provided with steel ball, while in adjusting screw and spring It is provided with safety valve spring between seat, the structure of dual spring can be realized the adjustment that triple-use valve carries out gap when in use, The using effect of triple-use valve is more good.
